The distributor guys should remember my thread last month where I sort of inherited a DP distributor from my friend with a 69 Hemi RR when he decided to keep his MSD distributor.
Without a long story the MDS just doesn't work and was shorting out the #1 plug wire to the underhood fresh air assembly and keeping the hood from closing all the way. It's 3 inch taller than a stock distributor and he was blowing a hole in the #1 Terminal boot about every time he drove it. So he went looking for another distributor and found one and I told him I could manage to rebuild this one too. He thinks it's a 67 Hemi distributor but who knows - tags can be swapped in a minute. The no. on the tag is 2642834.
Got it all apart and installed new bushings but got to looking at the cam stop and although the internals all look really nice - the cam just doesn't look right for the distributor. It's stamped LU and the slots are .475" long. The shaft is 39 LD, LAZ1039LD.
Does this sound right for a Hemi - that cam stop with the longer slots? The one I rebuilt earlier with an LB cam stop measured .400" in the slots for less mech advance.
He wants to plug the vacuum advance because that's what a Chevy racer/mechanic buddy he grew up with is telling him. But I'm afraid if the mech advance in this thing is 28 crank degrees or something like that and he can only time it initially at 8 degrees or so, it's going to run like a dog and heat up. It has a fairly mild hydraulic roller cam in it and a 4 speed/Dana 3.54. Does this sound like an incorrect cam stop? Is this tag even for a Hemi?
Thanks as always.
